ZoomTransform class

A class representing a zoom transformation with scale and translation.

ZoomTransform encapsulates the state of a zoom/pan operation, including the scale factor and translation offsets.

Constructors

ZoomTransform({double scale = 1.0, double translateX = 0.0, double translateY = 0.0}): Creates a ZoomTransform.
const
ZoomTransform.scale(double scale): Creates a ZoomTransform from a scale value.
factory
ZoomTransform.translate(double x, double y): Creates a ZoomTransform from a translation.
factory
ZoomTransform.translateOffset(Offset offset): Creates a ZoomTransform from an Offset translation.
